1500 x 3 = 4500 volt-amperes. Note: this answer does not take into consideration the circuits required for small-appliance and laundry loads; these must be calculated separately.

The metallic shielding should be stripped back to expose the wire enough to achieve a good termination connection, but should not interfere with other components in the box. The sheathing should a' remain on the wire where it is secured by cable clamps where the wire enters the panel

When circuit lines are drawn straight, they are sometimes confused with the building lines. Thus, Answer C is one good reason for drawing curved circuit lines.

A motor disconnecting means should be installed on the line side of the controller so that both the controller and motor are disconnected simultaneously. NEC Article 430.74.

Conduits are supported approximately every 5-6 ft. along the building wall. Fastener-failure may result in wires pulling away from the building, causing a potentially dangerous situation.

A junction box to house motor terminals shall be run, in general, in flexible or rigid metal raceway and must not be smaller than
3/8-inch electrical trade size. NEC Section 430.145(B).

Accessible as it pertains to equipment means that one may get into the equipment without obstruction, such as a locked or sealed or elevated door. Example: 'switches and CBs used as switches shall not be more than 67" from the floor."

At least one receptacle outlet to be installed in each basement and in each attached garage, or in each detached garage with electric power.

Electrical drawings resemble mechanical drawings using plan views for layouts, and details and schedules for clarifications. Electrical drawings include electrical power and lighting plans, telecommunications and any specialized wiring systems such as that for fire, emergency and security alarm and lighting systems.

Raceways enclose and protect bare wires, while cable trays provide support for electric wires that have adequate insulation and do not require the added protection. Open raceways only support the wires and are open to inspection and modifications. ' z Conduits, underfloor duct, wireways and surface metal raceways support insulated electric wire and provide protection.

NEC Sections 200.6(B) permits grounded conductors to be identified by a white or gray outer finish, or by three continuous white stripes along their entire length on other than green insulation. However, only sizes larger than No. 6 AWG are permitted to be marked as white or grey at points of termination and such markings must encircle the entire conductor.

The maximum number of overcurrent devices in a three-phase, 4-wire system is 42.

On a de circuit, voltage and current happen simultaneously, thus, the power factor is said to be at unity.
